Description

Technical Field

[0001] This invention belongs to the field of connector testing technology, and in particular relates to an automatic unloading system for connector testing. Background Technology

[0002] Automotive connectors are components frequently encountered by electronic engineers. Their function is quite simple: to bridge gaps in circuits or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. Automotive connectors come in a wide variety of forms and structures, but they are primarily composed of four basic structural components: contacts, housing, insulator, and accessories.

[0003] Automotive connectors rely on cameras, range sensors, and focus controllers to identify whether they meet the requirements. However, due to the small size of the connectors, it is difficult and costly to use robotic arms to collect defective products for storage during inspection. Therefore, most factories rely on manual handling to pick them up and put them into defective product boxes, which is too inefficient. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art and provide an automatic unloading system for connector inspection.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] This invention provides an automatic unloading system for connector inspection, comprising:

[0007] The testing platform has a discharge port;

[0008] A detection component is disposed above the detection platform;

[0009] A flipping assembly includes a feeding plate arranged circumferentially around the feeding port and capable of flipping in the direction of the feeding port;

[0010] And a feeding assembly, which includes a movable plate covering the feeding port, a transition plate perpendicular to the movable plate, and a linkage mechanism hinged to the transition plate and controlling the transition plate to move away from or towards the feeding port.

[0018] The flipping assembly also includes an ejector cylinder connected to one end of the first feeding plate. The ejector cylinder extends an ejector rod to drive the first feeding plate to flip toward the discharge port.

[0019] Furthermore, when the ejector rod of the ejector cylinder is not in operation, it is at the same height as the second discharge plate.

[0020] Furthermore, the maximum diameter of the discharge port is smaller than the maximum diameter of the movable plate.

[0021] Furthermore, the feeding port is circular in shape.

[0022] Furthermore, a defective product box is provided below the testing platform, directly opposite the movable plate.

[0075] Please see again. Figure 1 and Figure 2 As shown, when the ejector rod of the ejector cylinder 303 is not in operation, it is at the same height as the second discharge plate 303.

[0076] Please see again. Figure 1 and Figure 2 As shown, the maximum diameter of the discharge port 101 is smaller than the maximum diameter of the movable plate 401.

[0077] Please see again. Figure 1 and Figure 2 As shown, the material discharge port 101 is circular in shape.

[0080] Please see again. Figure 1 and Figure 2 As shown, the outer surface of the detection box 103 is provided with a door, and the bottom of the detection box 103 is provided with casters 104.

[0081] Please see again. Figure 1 and Figure 2 As shown, the detection component 2 includes a camera 201 mounted on the detection platform 1 and facing the feeding plate 301, an image recognition processor 202 mounted on the detection platform 1 and facing the feeding plate 301, a distance sensor 203 mounted on the detection platform 1 and facing the feeding plate 301, and a focal length controller 204 mounted on the detection platform 1 and facing the feeding plate 301. The image recognition processor 202 is connected to the camera 201, and the focal length controller 204 is connected to both the distance sensor 204 and the camera 201.

[0082] This embodiment also includes a control component, which is a computer. The computer has a first switch that is electrically connected to the tension cylinder 408 and a second switch that is electrically connected to the ejection cylinder 304. The computer is connected to the detection component 2.

[0083] The working principle of this embodiment is as follows:

[0084] Camera 201 captures images of the connector terminals. Image recognition processor 202 compares the captured images with standard connector images stored in the image memory to identify whether the connector terminals are deformed, missing corners, etc. Distance sensor 203 acquires the distance from camera 201 to the connector. Focus controller 204 controls camera 201 to capture images of the connector terminals at the optimal focus based on the distance, thereby adjusting the range and clarity of the images captured by camera 201 and providing assurance for subsequent image recognition and detection.

[0085] When a defective product is detected, the computer displays an instruction, and the worker uses the second switch to activate the ejector cylinder 304. The ejector cylinder 304 extends its ejector rod to lift the first feeding plate 302, causing the first feeding plate 302 to tilt. The connector placed on the first feeding plate 302 begins to slide down. Then, the worker uses the first switch to control the tension cylinder 408 to operate. The tension cylinder 408 drives the fourth connecting rod 407 to move to the lower left. At the same time, the third connecting rod 406, which is hinged to the fourth connecting rod 407, moves to the lower left. The third connecting rod 406 is hinged to the second connecting rod 405. Therefore, the second link 405 moves to the lower left. Since the second link 405 is hinged to the first link 404, and the first link 404 moves to the lower left, and since the first link 404 and the third link 406 are respectively hinged to the transition plate 402, the transition plate 402 moves to the lower left. Since the transition plate 402 is fixedly connected to the movable plate 401, the movement of the transition plate 402 to the lower left drives the movable plate 401 to move away from the discharge port 101. Therefore, the connector slides down the upper surface of the first discharge plate 302 into the defective product box.

[0086] The above description of the embodiments is provided to enable those skilled in the art to understand and use the invention. It will be apparent to those skilled in the art that various modifications can be made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present invention is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the invention should be within the protection scope of the present invention.
